Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and in particular to a seeder control system and a control method thereof based on satellite-ground combined enhanced Beidou positioning. Background Art

[0002] As a crucial piece of machinery in agricultural production, seed drills are widely used in large-scale planting operations. Traditional seed drills primarily rely on mechanical structures and simple control systems to accomplish seed sowing tasks. With technological advancements, modern seed drills have gradually integrated sensor technology, automatic control techniques, and data analysis algorithms, achieving more efficient and precise operations. Existing seed drill control systems typically use sensors to detect environmental factors such as soil moisture, temperature, and crop seed condition, and then adjust sowing parameters to achieve precise control over sowing depth, spacing, and density. These technologies have enhanced seed drill performance, enabling them to meet certain agricultural operational needs and promote the modernization of agricultural production. However, with the continuous advancement of agricultural modernization, traditional seed drills have gradually exposed numerous shortcomings that fail to meet the high-precision and high-efficiency demands of modern agriculture.

[0003] Currently, the core flaw of existing seed drill control systems is that they lack highly intelligent automatic adjustment capabilities. Existing seed drills suffer from insufficient positioning accuracy and inconsistent seeding depth and spacing in complex terrain and environmental conditions. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides a seed drill control system and a control method based on joint satellite-ground enhanced Beidou positioning. The technical problem to be solved by this invention is: how to achieve dynamic optimization of seed drill operating parameters and fault prediction through high-precision positioning and real-time environmental data collection and analysis.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a planter control system based on satellite-ground joint enhanced Beidou positioning, comprising:

[0006] The satellite-ground joint enhanced Beidou positioning module receives signals from Beidou satellites and ground base stations and enhances the positioning data in real time to provide high-precision planter location data;

[0007] a control module connected to the satellite-ground joint enhanced Beidou positioning module, and configured to adjust the operating parameters of the seed drill according to the high-precision position data, the operating parameters including seeding depth, seeding spacing, and seeding speed;

[0008] a sensor module configured to detect soil moisture, temperature, and crop seed status in real time, and feed the data back to the control module for automatic adjustment;

[0009] The display feedback module is configured to display the working status and environmental information of the planter and provide fault diagnosis and real-time alarm functions.

Using a satellite-ground joint enhanced Beidou positioning module to receive signals from Beidou satellites and ground base stations, and performing differential enhancement processing on the positioning data to obtain high-precision position data of the planter in real time;

[0018] Preferably, the working parameters include sowing depth, sowing spacing and sowing speed to ensure sowing accuracy.

[0019] Preferably, the adaptive algorithm in S4 dynamically optimizes the operating parameters of the seed drill, specifically comprising the following steps:

[0020] The S4.1 control module calculates the optimal parameters for sowing depth, sowing spacing, and sowing speed by performing a weighted analysis of the real-time collected soil moisture, soil temperature, soil type, and crop requirements. The specific formula is as follows:

Furthermore, by monitoring environmental data in real time and dynamically adjusting based on crop needs, this technical solution can automatically adapt to different soil and crop conditions, further improving the adaptability and efficiency of sowing operations.

This fault prediction and correction function significantly reduces downtime, improves operational continuity and stability, and reduces maintenance costs and manual intervention. This ensures the planter can operate efficiently and accurately in a variety of environmental conditions, thereby improving overall agricultural production efficiency.
